2021 Hyundai Palisade transmission problems

Filed Oct 20, 2026 · Engine, Transmission · CA

I am the original owner of a 2021 Hyundai Palisade SEL AWD (74,225 miles) reporting repeated engine shutdowns in traffic, severe rough idling, and an unresolved safety concern. The problem began XXX. I first brought the vehicle to Hyundai on XXX and have sought service approximately four times since June. Despite technicians stating they could not reproduce the issue, the engine stalled again on XXX after I picked it up from service. The dealership also instructed me to complete a 1,000-mile oil consumption test. When I returned after 750 miles, I was told I had returned too early. The engine subsequently shut off twice on XXX. Documented incidents: XXX 1:53 PM: Engine shut off on [XXX]. XXX, 5:38 PM: Engine shut off on [XXX]. XXX, 5:08 AM: Engine shut off at [XXX] exit, [XXX] XXX 11:35 AM: Engine stalled at [XXX]/[XXX]. XXX, 12:30 PM: Engine stalled at [XXX]/[XXX]; check engine light illuminated. XXX, 10:57 AM: Near-stall with severe rough idling at Los Gatos Farmers Market. After further rough idling, the check engine light remained illuminated. On XXX the dealership service advisor personally experienced severe rough idling and an apparent near-stall while moving my vehicle, with the check engine light on. I heard her acknowledge the issue. The vehicle remains at the dealership. I provided a written incident log and opened Hyundai case #XXX. Repeated engine shutdowns at intersections and freeway exits pose a serious collision risk. I request the federal safety agency investigate this potential safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Due to a known oil consumption issue the manufacture replaced the engine using a short block swap, they used the old fuel injectors and during the swap one of them failed, becoming stuck open. Now they refuse to fix it without me paying for labor. The failed fuel injector occurred immediately following a mandatory manufacturer engine replacement and poses a thermal/fire hazard.

My Palisade is burning oil at a rapid pace. I took it to the dealership and they said it was an acceptable level. I don't believe that to be correct. I have less than 100,000 miles on it.

In May 2025, I contacted Hyundai regarding excessive oil consumption in my 2021 Palisade. In June, Hyundai directed me to take the vehicle to a dealership for testing. Under TSB 23-EM-008H ([XXX]), a failed oil consumption test requires engine replacement. My vehicle is covered under Hyundai’s 10-year/100,000-mile powertrain warranty. I have provided complete maintenance records and receipts for every oil change since purchasing the vehicle. Despite this, Hyundai has repeatedly denied my claim, citing maintenance issues and gross negligence without justification. Hyundai’s own guidance states that oil changes may be performed every 7,000 to 10,000 miles under normal conditions. The repeated testing process has worsened the engine condition. In addition, the dealership has returned the vehicle with missing bolts, oil-related issues, and damage resulting from an improper rear window film installation. I have made numerous attempts to resolve this matter and obtain the warranty coverage to which I am entitled, but Hyundai and the dealership have failed to do so. I am requesting one of the following remedies: (1) a full engine replacement in accordance with the warranty and TSB requirements, (2) a replacement vehicle of equal or greater trim level, or (3) reimbursement of all costs associated with leasing, purchasing, maintaining, and repairing this vehicle. We purchased this vehicle based on Hyundai’s reputation, ratings, and promise of “America’s Best Warranty.” We still like the vehicle itself, but the ongoing mechanical issues and Hyundai’s handling of this claim have been unacceptable.

After emissions campaign 9c9, downshifting using paddle shifters on downhill grades, engine failing to maintain speed. Does not slow car down like it did before, seems like no compression. Fuel efficiency / emissions over traditional transmission braking, forcing drivers to use brakes more often to avoid high RPMs. Safety Risk: The lack of engine braking can lead to brake overheating or fade on long downgrades, lack of engine braking can lead to brake overheating or fade on long downgrades. Above is what Google found [XXX] ) when i put in some key words. Here is what i wrote to a [XXX] . my 2021 Hyundai Palisade Campaign 9C in your article about the 2022 having the same downshifting issues after the Emissions recall was done. Have you heard from other 2021 owners? I use the downshift for breaking/keeping my speed down to save the breaks here in the [XXX] , [XXX] , and [XXX] mountains. Does not function as designed. "Loss of engine braking" " High Engine Revving" Did go back to dealer and drove tech around lot. I called back later and nothing they can do. 5/12/26 Went to the dealer again, for an appointment. Dealer service manager said it working as designed. Bull, was not that way before. He said if i don't like it, trade in the car.. He also said that I can't compare the Palasade to the other cars that have manual shifting. bull. I said Why have them if they don't do anything... Tried to explain that I have been driving for over 40 years and have always downshifted every car. This was fine until the emissions recall. Got no place with the dealer. Contacted Hyundai Corporate last week, and they should be following up on Wednesday/tomorrow. 5/13/26 Left VM for Sales GM at Bowser today where i purchase the car. Wrote above and more to: [XXX] Contacting you now. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2021 Hyundai Palisade and have experienced a complete transmission failure that I believe Hyundai had prior knowledge of and failed to address. Before my warranty expired, I contacted the dealership several times to report transmission symptoms I was experiencing. I was told that because no diagnostic code had been produced at that time, there was nothing they could do. Eventually, my check engine light came on with a P0741 code — Torque Converter Clutch Circuit Performance. When I brought the vehicle in, the dealer flushed the transmission fluid, which came out dark and contaminated with metal particles. After running the vehicle, the fluid was still dark, indicating active internal damage already in progress. The dealership has now told me I need a full transmission replacement at my own expense. I am the second owner of this vehicle with approximately 105,000 miles. I have since learned that Hyundai issued Technical Service Bulletin #20-AT-005H-1 specifically addressing the P0741 code on the 2021 Palisade, instructing dealers to replace the solenoid and valve body harness. This repair procedure was never applied to my vehicle despite my early report of symptoms. I believe this is a known defect that Hyundai has failed to escalate to a recall, leaving consumers like me with thousands of dollars in repair costs for a problem the manufacturer was already aware of. I am requesting that the federal safety agency investigate this issue and consider whether a recall is warranted for the 2021 Hyundai Palisade.

The vehicle suffered a structural "seam leak" on the pressurized oil filter housing. This was verified by an authorized Hyundai dealer (Dealer XXX, Invoice #XXX). The failure is a structural crack in the housing component itself, not a maintenance-related seal or filter failure. This defect causes pressurized engine oil to spray directly onto the hot engine block while the vehicle is in operation, creating a severe and immediate fire hazard. Additionally, the rapid loss of oil and oil pressure poses a risk of sudden engine seizure or stalling at highway speeds, which could lead to a crash. Despite being a known manufacturing defect in a critical engine component, the manufacturer has refused to address the safety implications or offer a remedy.

We have been in Hyundai’s “oil consumption” protocol for the past 8-10 months. We’ve had 6 oil changes in that time. Each oil change was right a 1,000 miles. My engine is burning between 1.5 - 2.5 quarts of oil EVERY 1,000 MILES. They have been trying to drag this out not having to take ownership of the issue. After reading online, clearly there is an issue with 2021 Palisades and a recall needs to be issued.

My vehicle is burning oil at an excessive rate causing vibration when the oil is nearly depleted and an unsafe driving condition. The vehicle will burn nearly all the oil in approximately 1000 miles. This has happened repeatedly. It is widely known amongst Palisade owners and the subject of numerous online posts. In addition, the dealership has acknowledged widespread issues with an oil burning problem.

Vehicle experienced engine failure previously and received a Hyundai-installed replacement engine in February 2025. Replacement engine is now setting DTC P000A00 – Intake Camshaft Position Slow Response (Bank 1). Hyundai dealership master technician confirmed excessive variance between commanded and actual cam timing, indicating a VVT / cam timing failure controlled by oil and actuators. Hyundai is refusing to cover diagnosis and repair under replacement engine warranty and is requiring customer-paid tear-down despite fault originating within the engine assembly. Concern is for internal engine timing failure that may lead to engine damage or loss of power. This appears consistent with known Hyundai engine timing and oil control issues
